Embodiments of the present invention relate to food additives and supplements comprising tender inner core of the banana plant's trunk (banana plant stem inner tender core) fibers; methods of producing same and methods of using same in processed foods, e.g. fast food.

BACKGROUND

Obesity is a major health problem in the United States and other developed countries, where high fat diets are prevalent. In fact, a majority of the U.S. adult population is considered as overweight or obese when measured by body mass index (BMI) calculations. Additionally, over 400,000 deaths annually are attributed to obesity.

Many different approaches to deal with obesity have been proposed. Diet modifications and exercise are known to be effective, but compliance with both practices is very poor. Obesity is less prevalent among people who eat foods that are high in fiber. Fiber is a complex carbohydrate found in foods of plant origin that cannot be digested by the human body. And, while dietary fiber passes through the digestive tract unreacted, it is still an essential part of a healthy diet. In addition to preventing obesity, eating fiber rich food may reduce the risk of cancer, heart disease, diabetes, dyslipidemias and gastrointestinal disorders.

Despite the known health benefits of fiber, many people struggle to get the recommended amount of fiber through their normal diet. The palatability of fiber rich foods is at least partially responsible for this. As a result, there remains a need for fiber rich food products having an uncompromised taste profile.

Specifically, the fast food and processed food industries are continuously searching for additives which increase the fiber content of their products without compromising, inter alia, shelf-life, compatibility with other ingredients, taste and cost.

Embodiments of the present invention are designed to meet these and other needs.

The present inventor has discovered that, in some embodiments, the water content of the inner core impacts the concentration of inner core that can be used in a particular food product without undesirable effect. For example, when a dry powder or dehydrated (5-20 wt. % water content) form of processed inner core is used, it is difficult to add more than 5 wt. % of the inner core to a food product, without an impact on the taste or processibility.

Further, the processed inner core may be added to any food product, as a fiber additive replacement for protein, carbohydrate or fat. In some embodiments, the food additives described herein reduce the calorie content of a meal.

Embodiments of the present invention are designed to overcome some of the processing challenges faced by those who conducted prior work with fiber sources, e.g. enzyme reactions which result in an undesirable taste profile or decomposition of the inner core.

The invention will be described in greater detail by way of specific examples. The following examples are offered for illustrative purposes and are not intended to limit the invention in any manner. Those skilled in the art will readily recognize a variety of noncritical parameters, which can be changed or modified to yield essentially the same results.

EXAMPLES Example 1 Fried Product

Inner core of the banana plant stem is removed by peeling off the outer layers of the stem. The inner core is washed with water and cut into pieces or shapes as desired. The inner core is soaked in acidic water solution for up to 4 hours, to prevent browning. The inner core is then washed. The inner core is then boiled for up to 8 hours depending on the final product requirement. Water is drained and the inner core is dried to an extent sufficient to provide a water content of about 80 wt. %. The dried inner core is mixed with flour and spices and deep fried.

Example 2 Bread Product

Inner core of the banana plant stem is removed by peeling off the outer layers of the stem. The inner core is washed with water and cut into pieces or shapes as desired. The inner core is soaked in acidic water solution for 6 hours, to prevent browning. The inner core is then boiled for 1-2 hours depending on the final product requirement. Water is drained and the inner core is dried to an extent sufficient to provide a water content of about 80 wt. %. ⅔ cup sugar is dissolved in a vessel containing 1 cup warm water. 1.5 tablespoons of yeast is added to the vessel. 1.5 teaspoons of salt and one quarter cup vegetable oil are added to the vessel. Six cups of white bread flour is added to the vessel one cup at time. Processed dough is kneaded on a lightly floured surface until smooth. Dough is placed in an oiled bowl to coat, and then covered with a damp cloth. Dough is allowed to rise for about 1 hour. Dough is punched down and then kneaded for a few minutes. Dough is shaped into loaves and placed into an oiled loaf pan. Dough is allowed to rise for about 30 minutes, or until dough has risen 1 inch above pan. Dough is then baked at 350° F. (175° C.) for about 30 minutes. The final product comprises about 25 wt. % processed inner core.

Table 1 (below) describes the composition of a white bread which can be made in accordance with the process described in the preceding paragraph.

TABLE 1 Ingredient Amount (g) Flour 1000 Yeast 17 Brown Sugar 22 Salt 8 Processed banana stem inner core (75% water) 900 Milk 450

Samples prepared with higher concentrations of inner core and/or reduced water content result in less than desirable final products. For example, a product prepared with 25 wt. % processed inner core, having a water content of 60 wt. %, fails to rise to a sufficient extent and does not deliver the desired taste profile.

Example 3 Muffin Product

Two cups all-purpose flour, one tablespoon baking powder and one-half teaspoon of salt are mixed in a first vessel. To the mixture is added processed inner core of a banana plant stem having a water content of about 90 wt. %. Beat one large egg in a second vessel and add ¼ cup granulated sugar, one cup whole milk and ½ teaspoon vanilla extract to the second vessel. Four tablespoons of melted butter is slowly mixed in with the contents of the second vessel. The contents of the first vessel are mixed gently with the contents of the second vessel. The mixture is poured into a muffin pan and baked at 400° F. for about 20 minutes. The final product comprises about 30 wt. % processed inner core.

Table 2 (below) describes the composition of an exemplary white bread product which can be made in accordance with the process described in the preceding paragraph.

TABLE 2 Ingredient Amount Flour 200 g Vegetable oil  30 g Sugar 100 g Salt  7 g Baking Powder  24 g Processed banana stem inner core (90% water) 200 g Milk 100 ml Egg 1

Samples prepared with higher concentrations of inner core and/or reduced water content result in less than desirable final products. For example, a muffin product prepared with 30 wt. % processed inner core, but having a water content of less than 50 wt. %, results in a product that is bulky, too hard, and does not deliver the desired taste profile.

Example 4 Fast Food Meat Product

Described below in Table 3 is an exemplary fast food meat product of the present invention, which comprises the inner core of a banana plant stem, prepared according to an inventive method of the present invention.

TABLE 3 Ingredient Amount (g) Meat Source 450 Processed inner core of banana plant stem 450 (85% water content) Salt 7 Pepper 5 Preservative 0.01-0.05 Egg yolk 40 Mustard 15 Chopped onion 50 Bread crumbs 40 Worcestershire sauce 10

Meat products prepared with up to 40 wt. % of processed inner core of a banana plant stem (having about 90 wt. % water content) result in a product without a perceptible taste difference. However, products prepared with greater than 40 wt. % processed inner core of a banana plant stem and having a water content of less than 50 wt. %, have a more fibrous structure. The fibrous structure not only results in an undesirable taste, but the product is not stable; and once cooked, it separates into pieces.

Example 5 Fast Food Potato Product

Described below in Table 4 is an exemplary fast food potato product of the present invention, which comprises the inner core of a banana plant stem, prepared according to an inventive method of the present invention.

TABLE 4 Ingredient Wt. % Potato source 50-99 Processed inner core of banana plant stem  1-50 Canola oil 0.1-0.5 Dextrose 1-5 Sodium acid pyrophosphate 0.01-0.05 Citric acid 0.01-0.05 Dimethylpolysiloxane 0.01-0.05 Sodium chloride 0.01-0.05

Example 6 Tortilla Chips

⅓ cup processed inner core of the banana plant stem (having a water content of about 70 wt. %) and 1 cup of corn flour are mixed. To the flour and inner core mixture is added 4.5 ounces of water. A dash of salt is added to the mixture and formed into dough. Dough is wrapped in plastic wrap and allowed to sit for about 30 minutes. Dough is rolled into eight even-sized balls and flattened. Flattened dough is then grilled on a slightly oiled skillet until golden brown. Grilled product is then cut into desired shapes, spiced as needed and baked at about 400° F., for about 10-12 minutes. The final product comprises about 30 wt. % processed inner core.

Samples prepared with higher concentrations of inner core and/or a water content of less than 50 wt. %, result in dough that is difficult to process. In addition, samples prepared with a processed inner core having a water content of greater than 80 wt. %, without an adjustment in inner core concentration, result in dough that is heavy and requires additional processing.

Example 7 Freshly Prepared Product

Add 100 grams of processed inner core having 90 wt. % water content to a vessel containing two eggs. Beat lightly and add salt and pepper to taste. Place in a warm buttered skillet on medium heat and cook for 2-3 minutes or until eggs harden to the desired extent. The final product comprises about 50 wt. % processed inner core.
